New Generation Bio-Binder Formulation

Due to growing interest in sustainability, Kansas State University has initiated the search for a non-petroleum binder that could be used for asphalt mixtures. The objective of this study is to develop a modified asphalt binder from bio-fuel by-products and wastes that can be used as a replacement of bituminous binders derived from the fossil fuel crude. Initial investigations of the structure and physical properties of bio-fuel-derived heavy oils revealed unexpected chemical differences to petroleum-derived asphalt binders. A simple process for removing the unwanted polar groups from bio-fuel based oils by applying heat will be studied and optimized. Subsequent crosslinking of the bio-based asphalt materials will result in better binder properties, such as enhanced wettability, coating (adhesion) and resistance to aging (loss of volatiles).
